Based on the results, a snow water equivalent estimation model was developed. The model was used to estimate snow water equivalents in the Jozankei Dam, and resulted in the estimate with a higher level of accuracy than those based on snow surveys and existing models.}, pages = {465--470}, title = {航空レーザ測量を活用したダム流域の積雪深分布の推定}, volume = {18}, year = {2012}, yomi = {ニシハラ, テルマサ and ナカツガワ, マコト} }
